Cleaning up an iPhone 4 for resale

[casssax]

I did a search but didn't find anything so I'm asking here.

Any advice for the best way to clean up an iPhone 4 before trying to sell it?

I still have a month until I can upgrade but starting to think about it.

What's the best way to clean the stainless steel, get the dust out of the switches and generally detail it to look like new without damaging it or making it look worse?

Detail brush. It's like a toothbrush but softer. Can be gotten at an auto parts store. Got mine at Wal-Mart.

OR

Go to the section where the shop vacs are. They have a mini detail brush kit that you can get. Works great on all kinds of electronics and keyboards etc.

Mine all cleaned up for sale.
